城市土地集约利用评价信息系统架构研究

Design and implementation of evaluation information system of intensive urban land use

本文在探讨模型库系统、数据库系统、人机交互系统等三大部件设计的基础上,重点研究模型库中各模型的存储、调用、管理和维护机制。本文设计并实现了模型字典库与文件库相结合的混合管理方式来对模型进行统一组织和存储;由空间数据库子系统、模型库子系统,以及人机交互子系统三个部件所组成的两两相互作用的三角式网络结构。结果表明:软件系统模型及数据组织恰当,软件结构和功能设置合理,能有效地进行城市土地集约利用评价工作。

The purpose of this study is to design and develop the Information System served for the Intensive Urban Land Use Evaluation. This study employed the triangle architecture, IULU-EIS was designed separately as three parts, namely the model base sys- tem, the database system, and the human-computer interaction system. And this study focused on the storage, management and maintenance mechanisms of the model in the model base. This paper combined model dictionary library with file library to organize and store the models, and designed and implemented the triangle network structure of pairwise interaction between model base, spatial data base and interaction system. The results indicated that this system organized the model and data properly, set the software structure and function reasonably, it could meet the needs of work environment with the integration of spatial data and attribute data when evaluating the intensive urban land use level.
